flexfilelayout.c	NFS/pNFS: Report EINVAL errors from connect() to the server stable inclusion from stable-5.10.198 commit 25ae2b2fdb1239a90f42933a0f75f868d271bd98 category: bugfix issue: #I9SP3X CVE: NA Signed-off-by: wanxiaoqing <wanxiaoqing@huawei.com> --------------------------------------- [ Upstream commit dd7d7ee3ba2a70d12d02defb478790cf57d5b87b ] With IPv6, connect() can occasionally return EINVAL if a route is unavailable. If this happens during I/O to a data server, we want to report it using LAYOUTERROR as an inability to connect.

flexfilelayoutdev.c	pnfs/flexfiles: Fix misplaced barrier in nfs4_ff_layout_prepare_ds stable inclusion from stable-5.10.80 commit e94c59b64e6ceb7b78fcdcb9a927f7b07461fff4 category: bugfix issue: #I5AFE6 CVE: NA Signed-off-by: Yu Changchun <yuchangchun1@huawei.com> --------------------------------------- [ Upstream commit a2915fa06227b056a8f9b0d79b61dca08ad5cfc6 ] _nfs4_pnfs_v3/v4_ds_connect do some work smp_wmb ds->ds_clp = clp; And nfs4_ff_layout_prepare_ds currently does smp_rmb if(ds->ds_clp) ... This patch places the smp_rmb after the if. This ensures that following reads only happen once nfs4_ff_layout_prepare_ds has checked that data has been properly initialized.
